University of Missouri researchers have determined that a compound found in green tea (EGCG), and voluntary exercise, slows the progression of the disease in mice and may reverse its effects.

Interesting, considering the proven effectiveness of EGCG in the majority of early stage CLL patients in the Mayo trial.

"Alzheimer’s-affected mice given EGCG and allowed to exercise saw improvement in cognitive function, the researchers reported in the Journal of Alzheimer’s Disease. In addition, a decline in beta-amyloid levels was seen.

Inflammation has been linked to Alzheimer’s disease and recent studies have also suggested that adding antioxidants to the diet can also reduce the risk of developing the disease, according to the researchers."

And from the referenced full article:

"Consumption of natural products as potential remedies to prevent and treat diseases and to maintain human health is an ancient one, said Sun, who also serves as the director of the Alzheimer's Disease Program at MU funded by the National Institutes of Health. Future studies of green tea extracts and other botanicals, also known as nutraceuticals, are being explored at MU and through collaborations with other international institutions.

No mention of whether the liver function of the mice was tested or where they sourced their EGCG .

There's not much sense in determining that some nutraceuticals can improve our health if countries can't guarantee that marketed nutraceuticals contain the advertised active ingredients without contamination by pesticides, heavy metals and unnecessary filler ingredients:
